Sportback boot not opening off fob

[Bigbang]

Hello, so my problem is that my boot will not open on the boot button in the centre of my fob. 

It will unlock fine if pressing the unlock button twice to unlock all doors, 

if I used the centre button on the fob and pull it open instantly it will open.

ive noticed other a3’s pop their boot slightly when opened on the boot button so you can pull it open without pressing the soft touch button?

mine didn’t “pop” at all so I think this is the problem, so my question is what part is responsible for popping the boot slightly open?

Yours in behaving the same as mine which I believe to be perfectly normal. That's why the fob has a centre button.
